Five world rankings on the institutions of everyday life: education spending as a share of GDP, health spending per capita, the homicide rate, the incarceration rate and the suicide rate.

All five keep the top 30 by latest value, so who is in the table shapes the conclusion. Homicide and incarceration collect only the high end, and countries with the world's lowest rates are absent. Health spending collects the high end too, but only 15 countries reported in 2024 and the United States is missing — which is why the apparent leader changed, not because anyone overtook it.
